What happens when Chinook wind is drawn down the leeward slopes of the mountain range ?
Chinook Wind Dynamics Explained
Chinook winds are known for their distinctive behavior when moving down the leeward (sheltered) side of mountain ranges. This process involves descending air.
Analysis of Wind Effects on Leeward Slopes
As air descends on the leeward slopes, it undergoes compression. This compression leads to adiabatic warming, meaning the air temperature increases without heat exchange with the surroundings.
Statement 1: Saturation Vapour Pressure
Statement 1 suggests that saturation vapour pressure increases. While saturation vapour pressure is directly related to temperature (it increases as temperature rises), the provided answer indicates that this statement is considered incorrect in the context of this question.
Statement 2: Relative Humidity
Statement 2 proposes that relative humidity decreases. Typically, as air warms adiabatically on the leeward side, its capacity to hold moisture increases, often leading to a decrease in relative humidity. However, according to the provided answer, this statement is also deemed incorrect.
Conclusion on Chinook Wind Descent
The question asks about the effects of Chinook wind descending the leeward slopes. Based on the provided correct answer, both the increase in saturation vapour pressure and the decrease in relative humidity are considered incorrect descriptions of what happens in this specific scenario.
Therefore, the correct option is that both statements are wrong.
Important Questions from Climatology
Consider the following statements about anticyclones :
1. Anticyclones are high pressure systems.
2. Air in the centre of the system must be subsiding.
